Error with JDBC after drop table

I am doing some JSP web development using PostgreSQL as my backend. I use
the PostgreSQL JDBC driver that I got from http://jdbc.postgresql.org
<http://jdbc.postgresql.org>
While development I dropped a table and recreated it and added the data back
into it from a copy using PG_DUMP.

But now when I take a look at my JSP page it now says:

javax.servlet.ServletException: java.sql.SQLException: ERROR: Relation
"ntr_node_t" with OID 34821 no longer exists

I've restarted the database, and also restarted the TOMCAT web server but it
still gives that message. Does anyone know how I can get by this error
message?

Thank you for your time!
